Abstract

We discuss a possibility to observe fast secondary electrons ($\delta-$electrons) during nuclear $\beta^{-}$-decay in few-electron atoms and ions. Formulas for the corresponding probabilities and explicit expression for the energy spectrum of $\delta-$electrons are derived in the closed analytical forms.
